2月 10th, 2025 News

Introduction

Amine-based foam delay catalysts (AFD catalysts) are a functional additive widely used in the production of polyurethane foam plastics. Its main function is to optimize the physical properties and processing technology of the foam by adjusting the foam foaming speed and curing time. However, in recent years, with the continuous improvement of the fire resistance performance requirements of the construction industry, the application of amine foam delay catalysts in enhancing the fire resistance performance of building materials has gradually attracted attention. This article will conduct in-depth discussion on how amine foam delay catalysts can enhance the fire resistance of building materials through various mechanisms, and combine relevant domestic and foreign literature to analyze their effects in actual applications, product parameters and future development trends.

Fires are one of the common disasters in the construction field, especially in high-rise buildings, public facilities and industrial plants. Fires often cause huge casualties and economic losses. Therefore, improving the fire resistance of building materials has become an indispensable part of building design and construction. Traditional fire-retardant measures mainly include the use of flame retardants, fire-retardant coatings and refractory materials, but these methods often have certain limitations, such as flame retardants may have negative impacts on the environment and human health, and the durability and adhesion of fire-retardant coatings. Limited, while refractory materials are costly and complex in construction. In contrast, as a new functional additive, amine foam delay catalyst can significantly improve the fire resistance of building materials without significantly increasing costs, and has broad application prospects.

The basic principles and mechanism of amine foam delay catalyst

Amine foam retardation catalysts are a class of organic compounds containing amino functional groups, which are usually used to regulate the foaming and curing process of polyurethane foams. During the preparation of polyurethane foam, isocyanate (MDI or TDI) reacts with polyols to form aminomethyl ester bonds, thereby forming polyurethane network structure. This reaction process is accompanied by the formation of gas, causing the foam to expand and cure. Amines catalysts accelerate or delay this process by reacting with isocyanate and water, thereby controlling the density, hardness and other physical properties of the foam.

1. Mechanism of delayed foaming and curing

The main function of amine foam delay catalysts is to delay the reaction of isocyanate with water, thereby delaying the foaming and curing time of the foam. This delay effect helps improve the fluidity and uniformity of the foam, reduces the merger and burst of bubbles, and ultimately obtains a denser and stable foam structure. Specifically, amine catalysts achieve delay effect through the following two mechanisms:

  • Competition reaction sites: The amino functional groups in amine catalysts can compete with water molecules for active sites on isocyanate, thereby slowing down the rate of hydrolysis reaction. Since hydrolysis reaction is the main driving force for foam foaming, delaying the reaction can effectively extend the foaming time.

  • Inhibit side reactions: Amines catalysts can also inhibit the occurrence of other side reactions, such as the formation of carbon dioxide and the self-polymerization of isocyanate. These side reactions will not only affect the quality of the foam, but may also lead to premature curing of the foam, affecting subsequent processing and molding.

2. Effect on foam structure

The use of amine foam delay catalysts can not only delay the foaming and curing of foam, but also have a significant impact on its microstructure. Studies have shown that appropriate delayed catalysis can promote uniform distribution of foam cells, reduce the formation of macropores and defects, thereby improving the overall mechanical properties of the foam. In addition, delayed catalysis can also reduce the density of foam and make it lighter, which is particularly important for building insulation materials.

3. Synergistic effects with other additives

In practical applications, amine foam retardant catalysts are usually used in conjunction with other functional additives such as flame retardants, plasticizers and fillers to achieve better overall performance. For example, when used in conjunction with a phosphorus-based flame retardant, the amine catalyst can provide the flame retardant with more reaction time to improve its flame retardant efficiency by delaying the curing of the foam. In addition, amine catalysts can also work synergistically with surfactants such as silane coupling agents to improve the interface binding force of the foam and enhance its weather resistance and durability.

Mechanism of amine foam delay catalysts to enhance fire resistance of building materials

Amine foam delay catalysts have unique advantages in enhancing the fire resistance of building materials, which are mainly reflected in the following aspects:

1. Reduce the heat release rate

When a fire occurs, the heat release rate of the material (HRR) is one of the key factors that determine the spread rate of the fire. Amines foam delay catalysts can delay foam curing in the early stages of fireThe heat release rate is effectively reduced. Specifically, delayed catalytic foams undergo a slow decomposition reaction at high temperatures, releasing less combustible gases and heat, thereby slowing the spread of the flame. Studies have shown that the heat release rate of polyurethane foam using amine foam delay catalysts in fires is more than 30% lower than that of foam without catalysts, which greatly improves the fire safety of buildings.

2. Promote the formation of carbon layer

The carbon layer is a protective barrier formed by building materials in fires, which can effectively isolate oxygen and heat and prevent the flame from further spreading. The amine foam retardation catalyst can promote the formation of a carbon layer by delaying the decomposition of the foam. Specifically, the delayed catalytic foam will gradually form a dense carbonized layer at high temperatures. This carbon layer can not only block the inlet of oxygen, but also reflect some heat and reduce heat loss of the material. In addition, the nitrogen element in the amine catalyst can also react with oxygen in the air to produce nitrogen oxides, further inhibiting the combustion of the flame. Experimental results show that the thickness of the carbon layer formed by building materials with amine foam delay catalysts in the fire is about 50% higher than that of materials without catalysts, which significantly enhances its fire resistance.

3. Improve the heat resistance of the material

Amine foam retardation catalysts can also improve the heat resistance of building materials by improving the microstructure of the foam. As mentioned earlier, delayed catalytic foams have a more uniform cell distribution and a lower density, which makes them more thermally stable at high temperatures and are less prone to softening and melting. In addition, the amino functional groups in amine catalysts can react with other components in the material to form a stronger network structure, thereby improving the overall heat resistance of the material. Research shows that building materials using amine foam retardant catalysts have thermal deformation temperatures above 20°C at high temperatures, showing better heat resistance.

4. Improve the smoke toxicity of the material

The smoke produced in fires will not only cause serious harm to human health, but will also reduce indoor visibility and hinder escape. Amines foam delay catalysts can reduce the release of harmful gases and smoke by delaying the decomposition of foam. Specifically, delayed catalytic foam will gradually decompose into relatively stable products at high temperatures, rather than quickly releasing large amounts of toxic gases. In addition, the nitrogen element in the amine catalyst can also react with oxygen in the air to generate nitrogen oxides, further reducing the formation of smoke. Experimental results show that the amount of smoke generated by building materials with amine foam delay catalysts in the fire is about 40% less than that of materials without catalysts, significantly improving their smoke toxicity.

Product parameters and experimental data

In order to better understand the performance of amine foam delay catalysts in enhancing fire resistance performance of building materials, this paper compiles the parameters of some typical products and analyzes them in combination with experimental data.

Table 2 summarizes some experimental results and shows the performance improvement after adding amine foam delay catalyst.

It can be seen from Table 2 that after the addition of amine foam delay catalyst, the thermal release rate of polyurethane foam is significantly reduced, the thickness of the carbon layer is significantly increased, and the smoke generation is large.With less heat deformation temperature, it also increases. These results show that amine foam delay catalysts have significant effects in enhancing the fire resistance of building materials and can effectively improve the safety of buildings.

Amines foam delay catalyst: The secret to better protecting electronic consumer goods

2月 10th, 2025 News

Introduction

Amine foam delay catalysts play a crucial role in the protection of modern consumer electronics. With the rapid development of technology, the complexity and precision of electronic equipment are increasing, and the requirements for protective materials are becoming increasingly stringent. Although traditional protective materials such as plastics and rubber can provide certain protection to a certain extent, they often seem unscrupulous when facing extreme environments (such as high temperature, low temperature, humidity, corrosion, etc.). Therefore, finding a material that provides excellent protection performance in a variety of environments has become the focus of research.

Amine foam delay catalysts emerged. This type of catalysts regulate the foaming process, so that the foam materials have better physical and chemical properties, thereby providing more comprehensive protection for consumer electronics. Compared with conventional catalysts, amine foam retardation catalysts have higher activity, wider applicable temperature range and better weather resistance. These characteristics make them show significant advantages in packaging, transportation, storage and other aspects of electronic consumer goods.

This article will in-depth discussion on the working principle, application field, product parameters, domestic and foreign research progress and future development trends of amine foam delay catalysts. Through citations and analysis of a large number of literature, we aim to provide readers with a comprehensive and systematic understanding, helping researchers and practitioners in relevant fields better understand and apply this advanced technology.

1. Working principle of amine foam delay catalyst

Amine foam delay catalyst is a special chemical substance. Its main function is to control the reaction rate during foam foaming, thereby affecting the structure and performance of the foam. Its working principle can be explained in detail from the following aspects:

1.1 Chemical structure and function of catalyst

Amine catalysts are usually composed of organic amines or derivatives thereof, and common ones include tertiary amines, secondary amines, primary amines, etc. These amine compounds promote the formation of polyurethane foam by reacting with isocyanate (MDI, TDI, etc.). Specifically, amine catalysts can accelerate the reaction between isocyanate and water to generate carbon dioxide gas, thereby promoting the expansion of the foam. At the same time, amine catalysts can also promote the reaction between isocyanate and polyols, form a polyurethane network structure, and impart excellent mechanical properties to the foam material.

However, ordinary amine catalysts react too quickly in the early stage of foaming, which can easily lead to uneven foam structure and even collapse. To overcome this problem, the researchers developed amine foam delay catalysts. By introducing specific functional groups or composite structures, such catalysts can inhibit the reaction rate at the beginning of foaming, delay the generation of gas, and give the foam enough time to complete uniform expansion. Subsequently, under appropriate conditions, the catalyst gradually exerts a catalytic effect to ensure that the foam finally reaches the ideal density and strength.

1.2 Reaction kinetics and delay mechanism

The core of amine foam retardation catalysts is its unique reaction kinetic characteristics. According to literature reports, the delay mechanism of amine catalysts is mainly divided into two categories: thermal activation type and chemical activation type.

  • Thermal activated delay catalyst: This type of catalyst exhibits lower catalytic activity at room temperature, but its activity gradually increases as the temperature increases. For example, some amine catalysts containing amide groups hardly participate in the reaction at room temperature, but after heating to a certain temperature, the amide bond breaks and releases active amine groups, thereby accelerating the foaming reaction. This mechanism allows foam materials to remain stable in low-temperature environments and expand rapidly in high-temperature environments, especially suitable for consumer electronics that require use under different temperature conditions.

  • Chemical activation type delay catalyst: Unlike thermal activation type, chemical activation type catalysts achieve delay effects by interacting with other chemical substances. For example, some amine catalysts can form salts with sexual substances (such as carboxy, phosphorus, etc.). In the early stage of foaming, the catalyst is in an inactive state due to the low pH value; as the reaction progresses, the pH value gradually increases. The catalyst restores activity and promotes the expansion of the foam. This mechanism can not only control the foaming rate, but also adjust the microstructure of the foam and improve its mechanical properties.

1.3 Optimization of foam structure

The application of amine foam delay catalysts is not limited to controlling the foaming rate, but also significantly improves the microstructure of the foam. Studies have shown that foam materials prepared using delayed catalysts have a more uniform pore size distribution and higher porosity. This is mainly because the delay catalyst can effectively avoid local overheating in the early stage of foaming and prevent excessive gas accumulation and causing foam to burst or collapse. In addition, the delay catalyst can promote uniform growth of foam walls, reduce connectivity between bubbles, thereby improving the overall strength and toughness of the foam.

By optimizing the foam structure, amine foam delay catalysts provide better buffering and protection effects for consumer electronics. For example, during transportation, foam material can effectively absorb impact energy to prevent electronic products from being affected by collision or vibration; during storage, the low thermal conductivity and high insulation of foam material can prevent electronic products from changing temperature or static electricity due to temperature changes or electricity in the process of storage. Accumulate and damage.

1.4 Environmental adaptability and durability

In addition to improving the physical properties of the foam, amine foam delay catalysts also impart better environmental adaptability and durability to the foam material. Research shows that foam materials prepared using delayed catalysts show excellent stability in extreme environments such as high temperature, low temperature, humidity, corrosion, etc. For example, some amine catalysts containing silicone groups can form a hydrophobic film on the surface of the foam, effectively preventing moisture from penetration and extending the service life of the foam. In addition, amine catalysts can also work synergistically with additives such as antioxidants and ultraviolet absorbers to further improve the anti-aging properties of foam materials.

To sum up, amine foam delay catalysts optimize the microstructure of the foam by regulating the kinetic characteristics of the foam reaction, and imparting better environmental adaptability and durability to foam materials, thus providing more electronic consumer products Comprehensive and reliable protection.

2. Application areas

Amine foam delay catalysts have been widely used in many fields due to their unique performance advantages, especially in the protection of consumer electronics. The following are the main application areas and specific application scenarios of amine foam delay catalysts:

2.1 Packaging and transportation of consumer electronic products

Electronic consumer goods such as smartphones, tablets, laptops, etc. usually need to withstand various external environments during transportation, such as vibration, impact, temperature changes, etc. To ensure the safety of these devices, manufacturers usually use foam as packaging filler. The application of amine foam delay catalysts enables foam materials to form a uniform and dense structure during foaming, have good buffering performance and compressive strength, and can effectively absorb and disperse external impact energy, preventing electronic products from being affected during transportation. damage.

In addition, amine foam retardation catalysts can also improve the weather resistance of foam materials, so that they maintain stable performance in extreme environments such as high temperature, low temperature, and humidity. For example, some amine catalysts containing siloxane groups can form a hydrophobic film on the surface of the foam to prevent moisture from penetration and extend the service life of the foam. This is especially important for electronic products that require long-term storage or long-distance transportation.

2.2 Packaging and protection of electronic components

Electronic components such as integrated circuits (ICs), transistors, capacitors, etc. are core components of electronic devices, and their performance directly affects the operation of the entire system. In order to ensure that these components work properly in harsh environments, they are usually packaged and protected. Amines foam delay catalysts are also widely used in this field. Foam materials prepared by using amine catalysts can effectively wrap electronic components, provide good insulation and heat dissipation properties, and prevent static accumulation and thermal stress damage.

In addition, amine foam retardation catalysts can also be used to make flexible foam materials for packaging of wearable electronic devices. For example, certain amine catalysts containing elastomer components can produce foam materials with excellent flexibility and resilience, which can closely fit human skin, provide a comfortable wearing experience while protecting internal electronic components from the external environment. .

2.3 Protection of batteries and energy storage equipment

With the popularity of energy storage equipment such as electric vehicles and portable power supplies, the safety and reliability of batteries have become the focus of people’s attention. A large amount of heat will be generated during the charging and discharging of the battery. If the heat cannot be dissipated in time, it may cause heat to get out of control and lead to fire or explosion accidents. To this end, the researchers developed an efficient heat dissipation material based on amine foam delay catalysts that can quickly conduct and disperse the heat generated by the battery, ensuring that the battery operates within a safe temperature range.

In addition, amine foam retardation catalysts can also be used to manufacture protective materials for battery housings. Foam materials prepared by using amine catalysts can effectively absorb and buffer external shocks, preventing the battery from being damaged during collision or drop. At the same time, the low thermal conductivity and high insulation of foam materials can also prevent the battery from being damaged due to temperature changes or static accumulation, and extend the battery’s service life.

2.4 Electromagnetic shielding of communication equipment

With the development of new technologies such as 5G and the Internet of Things, the electromagnetic compatibility (EMC) problem of communication equipment is becoming increasingly prominent. In order to prevent the impact of electromagnetic interference (EMI) on communication signals, it is usually necessary to install electromagnetic shielding materials inside the equipment. Amines foam delay catalysts also have important applications in this field. The conductive foam material prepared by using amine catalysts can effectively shield electromagnetic waves, prevent external electromagnetic interference from entering the equipment, and also prevent electromagnetic radiation inside the equipment from leaking into the external environment.

Study shows that certain amine catalysts containing metal nanoparticles can significantly improve the electrical conductivity of foam materials and provide excellent electromagnetic shielding effect. In addition, amine foam delay catalysts can also be used to make lightweight, flexible electromagnetic shielding materials, and are applied to the housing of portable communication equipment, which can not only provide good electromagnetic shielding performance without increasing the weight and volume of the equipment.

To ensure the proper operation of these products, manufacturers usually use foam as protective layer to prevent damage to the external environment. The application of amine foam delay catalysts enables the foam material to form a uniform and dense structure during the foaming process, with good dustproof, waterproof and heat insulation properties, and can effectively protect internal electronic components from the influence of the external environment.

In addition, amine foam delay catalysts can also be used to make antibacterial and mildew-resistant foam materials, and are used in household appliances in humid environments such as kitchens and bathrooms. By introducing antibacterial agents or anti-mold agents into amine catalysts, it can effectively inhibit the growth of bacteria and mold, extend the service life of home appliances, and ensure the health and safety of users.

Current Situation and Challenges of Climate Change

Climate change refers to the long-term trend of the earth’s climate system, mainly including rising temperatures, changing precipitation patterns, frequent occurrence of extreme weather events. According to a new report from the United Nations Intergovernmental Panel on Climate Change (IPCC), global average temperatures have risen by about 1.1 degrees Celsius since the Industrial Revolution, and this heating rate will continue in the coming decades. The impact of climate change is multifaceted, covering many areas such as natural ecosystems, human social and economic activities, and global health.

First, climate change has caused serious damage to natural ecosystems. Global warming has caused melting glaciers and rising sea levels, threatening the ecological balance and residents’ lives in coastal areas. At the same time, the frequency of extreme weather events such as heavy rain, drought, hurricanes has increased, causing huge losses to industries such as agriculture, forestry, and fishery. Biodiversity is also declining, and many species are at risk of extinction, which not only affects the stability and function of the ecosystem, but also weakens the earth’s ability to self-regulate.

Secondly, climate change has had a profound impact on human social and economic activities. Increased energy demand, intensified food security issues, and damage to infrastructure have all brought tremendous pressure to the global economy. Especially for developing countries, the impact of climate change is more prominent, and these countries often lack sufficient resources and technologies to address the challenges brought about by climate change, which further worsens poverty, hunger, disease and other problems.

After, climate change poses a serious threat to global health. High temperature weather, air pollution, water shortage and other problems have increased health risks such as infectious diseases and cardiovascular diseases. Research shows that climate change may lead to the expansion of the spread of tropical diseases such as malaria and dengue, posing new challenges to the global public health system.

Faced with the severe situation of climate change, the international community generally recognizes that active and effective measures must be taken to mitigate the speed of climate change and adapt to the impacts of climate change. To this end, governments and international organizations have formulated a number of policies and agreements, such as the Paris Agreement and the Kyoto Protocol, aiming to achieve global temperature increase control by reducing greenhouse gas emissions, promoting clean energy, and improving energy efficiency. Within 2 degrees Celsius, even efforts are made to limit the heating to 1.5 degrees Celsius.

However, there are still many challenges to achieve this. First of all, there are technical bottlenecks. Although significant progress has been made in renewable energy, energy-saving technology, etc., there are still technical difficulties in some areas, such as building insulation, industrial insulation, etc., and further innovation and breakthroughs are needed. The second is the cost issue. The research and development, production and promotion of low-carbon technologies and products require a large amount of capital investment. How to achieve environmental benefits while ensuring economic benefits is an urgent problem. In addition, the public awareness enhancement?? is also crucial. Only when all sectors of society fully recognize the harm of climate change and actively participate in response actions can the goals of global climate governance be truly achieved.

To sum up, climate change is not only an environmental issue, but also a major issue involving global sustainable development. In the face of this challenge, we need to start from multiple angles, comprehensively use policies, technology, economic and other means to jointly respond to climate change and protect the earth’s home.
